Waste-tire recycling system

Abstract

Disclosed is a system for recycling waste tires, which are industrial wastes, so as to protect our environment against pollution and promote recycling of industrial material. The waste-tire recycling system includes a pyrolyzing unit for pyrolyzing a waste tire by using a pyrolysis reactor, in which a CO or N gas circulates as a carrier gas, a decomposed residue processing unit for crushing a decomposed residue pyrolyzied by the pyrolysis reactor to separate the decomposed residue into carbon and an iron core, an oil collecting unit for cooling and condensing an exhaust gas discharged from the pyrolysis reactor to recover heavy oil from the gas, a carbon processing unit for supplying a heat source to the circulating carrier gas by using a hot exhaust gas generated when the carbon separated from the decomposed residue is burned up, and operating a steam turbine and an absorption refrigerator to generate electricity and cold water, an exhaust gas processing unit for clarifying the exhaust gas discharged from the carbon processing unit to discharge the clarified gas in an atmosphere, and recovering a part of the CO or N gas from the exhaust gas.

Description

TECHNICAL FIELD[0001]The present invention relates to a system for recycling waste tires which are industrial wastes, so as to protect our environment against pollution and promote recycling of industrial material, and more particularly, to a waste-tire recycling system using carbon dioxide or nitrogen gas as a carrier gas to prevent the system from exploding due to a direct heating manner when waste tires are recycled, by which oil, scrap iron, electricity, cold water, carbon dioxide, and nitrogen can be obtained from a decomposed residue and an exhaust gas.BACKGROUND ART[0002]Rapid increase of automobiles results in increased demand of tires. As a result, the number of tires wasted due to its completed lifespan or damage in use is increased.[0003]Further, the waste tires are increased in proportion to the number of automobiles. Hence, the waste tires cause serious environmental pollution. However, most of the waste tires are not recycled, but come into disuse.[0004]The disposal of...

AI Technical Summary

Benefits of technology

"The present invention relates to a waste-tire recycling system using carbon dioxide or nitrogen as a carrier gas to prevent explosions during the pyrolysis process. The system includes a pyrolysis reactor, decomposed residue processing means, oil collecting means, carbon processing means, and exhaust gas processing means. The system can recycle waste tires by pyrolysis, and obtain various products such as oil, scrap iron, electricity, cold water, carbon dioxide, and nitrogen. The invention solves the problem of waste tire disposal and promotes recycling of industrial materials."

Problems solved by technology

As a result, the number of tires wasted due to its completed lifespan or damage in use is increased.

Hence, the waste tires cause serious environmental pollution.

However, most of the waste tires are not recycled, but come into disuse.

The landfill of the waste tires requires a wide area of landfill site, and also causes pollution of soil and underground water.

Further, the incineration of the waste tires causes serious air pollution due to incomplete combustion.

Diverse recycled products such as pavement block or artificial fishing reef have been proposed and used at present, but are still insignificant.
